How can I optimize performance in Formik?
To optimize performance in Formik, consider using the FastField
component for fields that don't depend on each other.
What are the benefits of using FastField?
FastField
only re-renders when its value changes, which can significantly reduce the number of re-renders in large forms.
Are there any other techniques I should know about?
Yes, you can also use useFormikContext
to access Formik state without re-rendering the entire form.
How does useFormikContext
help with performance?
It allows you to access Formik's context without causing unnecessary re-renders, improving overall performance.
